| Notes | Model 4-T-51 chassis5403 early uses the same cabinet as model 4-P-51, model 4-T-51 chassis 5401 ,model 4-T-51 chassis 5403 late, and model 4-V-59, chassis 5405. Riders says the models use two wavebands, broadcast 550-1600kc. and shortwave 1550-3650kc. Model 4-T-51 after serial number 54439 uses the wave bands broadcast 545-1600kc. and shortwave 1520-4850kc. Model 4-V-59 has a round dial. Model 4-P-51 has a cornered dial. The dial for the 4-T-51 models may be either round or cornered. Both dials are found in Zenith images. Maybe the 4-T-51 chassis 5403 late began with the round dial. |
